Short-Term Scientific Missions

Short-term scientific missions (STSM) are exchange visits between researchers involved in a COST Action, allowing scientists to visit an institution or laboratory in another COST country. They are aimed at fostering collaboration, sharing new techniques and infrastructure that may not be available in other participants' institutions or laboratories. STSM are intended especially for young researchers. 

Visit periods should last between 5 and 90 calendar days.
The applications have to be relevant to the objectives of this specific COST ACTION!

 

Please follow this link to apply for a short-term scientific mission (link opens in new window - an e-COST profile is required and can be created if needed).

3rd call for Short Term Scientific Missions

This call is opened by means of creating this exchange platform to publish STSM opportunities themed by hosts.

STSMs should be planned to take place in a period before the end of GP-2 (30/04/2020).

The Senseco MC has allocated funding for 12 STSMs in the Work and Budget Plan.

Title: Time-series analysis from VENµS and Sentinel-2for monitoring desert phenology and separating vegetation components

Background: At the Volcani Center, Israel. We have field observations of vegetation components and weather data from several study sites in the Negev desert and VENµS data access. 

Description: This STSM aims at succeeding for the first time to use satellite remote sensing data to separate the “greenness” signal from biological soil crusts, annual herbaceous vegetation, and perennial shrubs. This was previously demonstrated by field spectroscopy but clear sky satellite imagery at the critical times during the season were not available until recently. During the STSM you will work together with the members of the Rozenstein lab to perform the image processing, analysis of links of remote sensing with the field and weather data, and write a paper. 

•The grantee should have a solid understanding satellite data processing from sources such as Sentinel 2

Title: Uncertainty in field measurements

Description: No measurement is complete without an uncertainty statement. This STSM is concentrating on propagating uncertainties of field spectroradiometric measurements to the estimated reflectance factors. Data and metadata is available in our in-house spectral database SPECCHIO, covering dozens of field campaigns to support the CAL/VAL of the APEX airborne imaging spectrometer. Join our team for a few weeks to compute uncertainties on reflectances, learn about uncertainty propagation and implement some code interfacing the spectral database.

Duration 4-8 weeks

Title: Sentinel-2 reflectance-based metrics to track SIF heterogeneity at FLEX spatial scale

Background: Within the context of the future ESA FLEX mission, a number of activities are being performed to better understand and exploit the solar-induced fluorescence (SIF) signal. In the last years, a large amount of airborne reflectance/fluorescence data has been collected during several campaigns across Europe and the US, over large areas in a variety of different ecosystems. This dataset offers a great chance to investigate the spatial heterogeneity of SIF in natural and agricultural landscapes and to address key question towards the FLEX calibration/validation activity.

Description: In the frame of this STSM the candidate will use an existing set of airborne hyperspectral reflectance/fluorescence data collected within recent ESA-FLEX campaigns, together with Sentinel-2 L2a surface reflectance data. 

The main aim of the project will be to test Sentinel-2-based metrics that can explain the fluorescence spatial heterogeneity at medium spatial resolution (e.g., 300m x 300m, 2km x 2km), within the context of the FLEX mission cal/val activities. 

The candidate should have experience in handling spatial data and in basic geostatistics. Programming skills for batch data processing would also be beneficial.

This STSM can start at any time but shall have a minimum duration of 2-3 months.

Title: Leaf spectral dynamics’ monitoring in response to stress

Background: Leaf reflectance, transmittance and emitted fluorescence measurements are essential ground measurements for understanding the top-of-canopy signal from vegetation. The signals allow us to obtain information on how energy is absorbed in the photosynthetic active radiation range (PAR, 400-750 nm) and further used. The Laboratory of Earth Observation (LEO) of the University of Valencia has a strong background in the protocols for measuring the leaf radiative fluxes by means of the FluoWat leaf clip with attached high-spectral resolution spectroradiometers. 

Description: Depending on the research aims of the STSM candidate, different measuring protocols can be set or developed. A leaf spectroscopic experiment can be carried either under solar or artificial light conditions to study the dynamics of light harvesting, fluorescence emission and regulated heat dissipation at leaf level. The main aim is (1) to investigate the full spectral information and the diurnal dynamics due to light acclimation and/or a specific type of stress, and (2) to propose guidelines for the monitoring of dynamic spectral changes due to stress, taking in consideration data quality and metadata requirements.      

The candidate is familiar with the basic understanding and concepts of leaf spectroscopy, photosynthesis and photoprotection. Programming skills are beneficial for data processing.

This STSM can start from March 2020 and shall have a minimum duration of 1-2 months.
